Each vm guest was started with a command similar to the following:
sudo env ETHER=bnx1 qemu \
-net nic,vlan=0,model=rtl8139,macaddr=AA:BB:CC:DD:EE:XX \
-net tap,vlan=0 -m 384 -no-fd-bootchk -localtime \
-hda whatever.img -nographic
XX was F1, F2, F3, and F4 w2k3, w2k, appint and appext images respectively
I used nographic because it was easier to use rdesktop and rdp from other
systems to access the vm guests instead of being at the console.
Do you notice any performance gains by running them like this? I'm
running one instance of XP on a dual-core box with 4GB of RAM, and
it's slow as hell. I'd try running Windows 7, but the ACPI fails, and
I can't allocate 1GB of RAM with the version we have in ports to do
the initial install.
I don't use kqemu but have had satisfactory performance with Windows XP
running on top of qemu.
For me default settings have worked very well and I have not tried to
allocate 1GB etc. to a process or done anything fancy. I may have
changed login.conf modestly so that I got higher ulimits but that would
have been the extent of my tweaking. At that time, Windows 2000 and XP
performed quite well with -m 384 (W2K was running SQL Server and IIS).
Windows 2003 did not perform well with -m 384 but was OK for testing
purposes with -m 448.
In all cases, at that time I found invoking qemu with -nographic and
accessing through RDP or rdesktop to be better for usability and
performance.
I am not sure but may be there was a correlation with running multiple
versions of Windows using qemu. I am saying this because I use OpenBSD
4.6 -stable AMD64 as my main desktop machine and here I have qemu with a
copy of Windows XP. This is mainly for my wife so that she can run the
one Windows program she uses. XP is definitely not slow on this system
(whether accessed through rdesktop or through KDE) and so far have not
had any complaints/problems.
HTH,
